Sugar, the sweetest decision maker at work

WE'VE all been there. It's that time of the day when our energy levels slump and we just can't seem to make that all important work decision.

The solution according to one online author and marketing guru is to eat - and have sugar.

Canadian Herbert Lui reckons the key to better and more level-headed decision making is glucose.

Mr Lui says studies have repeatedly shown the link between constant glucose levels in people's blood and the ability to make good decisions.

Citing one study from Willpower, written by university professors Roy F. Baumeister and John Tierney, Mr Lui said research showed how people became less angry with glucose in their systems.

In this study, participants were given lemonade mixed either with sugar or with a diet sweetener while playing a virtual game - with neither told which they were drinking. Those given the artificial sweetener were far more likely to become angry than those given sugar.

"It has been proven that when our glucose levels are replenished, it becomes much easier to consistently endure trials and to make tough decisions,” he writes.

And workers shouldn't underestimate their need for sleep either, Mr Lui adds, writing that sleep is the first activity that gets sacrificed as entrepreneurs find their workloads picking up.

Getting enough rest helps reduces "the body's demand for glucose and improves its overall ability to make use of the glucose in the bloodstream” he adds.
